Changing a value in SQLite3
提问by james
I'll start off by showing the code:
我将首先展示代码：
create table products ('name' text primary key, 'price' INTEGER)
insert into table products ('name', 'price') values ('coke', 8)
insert into table products ('name', 'price') values ('sprite', 9)
What would be the SQLite3 code to change the value of the price column for the coke row to 12.
So I want the output to be coke 12 sprite 9.
将可乐行的价格列的值更改为 12 的 SQLite3 代码是什么。
所以我希望输出是可乐 12 sprite 9。
Thanks alot guys!
非常感谢各位！

UPDATE products
SET price = 12
WHERE name = 'coke' AND price = 8;
These might just be transcription errors or typos, but you should remove the word tablefrom your INSERTstatements, and you don't need single-quotes around column names, so the statement should look like:
这些可能只是转录错误或拼写错误，但您应该table从INSERT语句中删除该词，并且列名不需要单引号，因此语句应如下所示：
insert into products (name, price) values ('sprite', 9)
